资源型城市经济发展与环境污染关系研究——以衡阳市为例

Relationship between economic development and environmental pollution in Resource-based City——A case study of Hengyang, Hunan Province

为促进衡阳市经济与环境协调发展,采用环境库兹涅茨曲线(EKC)对衡阳市经济发展与环境污染水平的关系进行定量研究,以衡阳市2004-2016年人均GDP为经济指标,以废水排放总量,废气排放总量,工业固体废物贮存量为环境指标。结果表明:衡阳市人均GDP与环境污染未呈现倒"U"型环境库兹涅茨曲线。人均GDP与工业废水排放量及工业固体废弃物产生量的EKC曲线表现为倒"N"型的三次曲线特征,且均已通过倒"N"型的峰值,说明衡阳市工业废水排放量和工业固体废弃物产生量会随着经济增长呈现下降趋势。人均GDP与工业废气排放量呈现较弱的"S"型,无明显峰值和拐点,且呈现上升趋势,说明衡阳市工业废气排放量会随着经济增长呈现增长趋势。结合衡阳市实际,提出促进衡阳市经济与环境协调发展的对策和建议。

In order to improve the coordinated development of the economy and the environment of Hengyang City.Based on statistical data of per capita GDP growth and environmental pollution index from 2004 to 2015,the relationship between the environmental pollution and economic development had been quantitative studied,using to the Environmental Kuznets Curve.The result showed that per capita GDP and environmental pollution is not consistent with the general"inverted U type"Environmental Kuznets Curve in Hengyang City.It presented the"inverted N type"characteristics between total volume of industrial wastewater discharged,the volume of industrial waste gas discharged and per capita GDP.It presented unconspicuous"S type"characteristic between the volume of industrial solid waste produced and per capita GDP,the inflexion was unconspicuous,and presented increasing trend.Based on practical condition of Hengyang City,the paper put forward countermeasures and suggestions of green development.
